A metering subassembly for use with a modular EGR valve 40 includes a metering subassembly 10 having an elongate metering shaft 14. A flanged end 24 of the metering shaft is disposed a predetermined distance above a top surface 30 of the metering subassembly 10. The metering subassembly 10 is configured for being coupled to an actuator subassembly 42 such that the flanged end 24 of the metering shaft 14 is disposed proximate the actuator subassembly. A gas arrestor 32 includes a side wall 34 interconnected with a collar 36. The collar surrounds a periphery of the flanged end 24. The side wall 34 extends from the collar 36 in a direction generally toward the top surface 30 of the metering subassembly 10. <IMAGE>
